To all whom t may concern.' Y

Be it known that we, EMIL KRAEMER and GEORGE SOHULER, both citizens of the United States of America, residing at Woodside, Queens county, and State of New York, have invented certain new and useful Improvements in Adjustable Window-Screens, of which the following is a full, clear, and eXact description.

This invention relates to improvements in adjustable window screens including rollers therefor and a housing for the rollers and screen.A One of the objects of our invention is to provide a screen and roller therefor arranged for longitudinal adjustment, thereby enabling the said screens and rollers to be applied to windows of diierent widths. Further features of our invention include a novel manner of connecting thel screen to a window, and also a novel manner of connecting the vscreen roller and housing therefor. Other points of improvement and advantages resulting from our invention will hereinafter appear.

W'e will now proceed to describe our invention in detail, the essential features of which will be summarized in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a top plan detail view of our improved roller for window-screens, illustrated as extended;

Fig. 2 is an enlarged longitudinal sectional view thereof partly in elevation;

Fig. 3 is a detail view of the roller and attached screen sections;

Fig. 4 is a cross-sectional view, on an enlarged scale, the section being taken on a line 4-4 in Fig. 3, the housing for theroller being also shown in section; j

Fig. 5 is an enlarged sectional detailview illustrating the housing and roller carried thereby;

Fig. 6 is an enlarged sectional detail view illustrating a manner of connecting the roller housing to a window-frame;

Fig. 7 is a' face viewV of thek housing bracket; i

Fig; 8 is a top plan view thereof;

Fig. 9 is a face view of that end of the roller housing which is engaged the spring spindle;

Fig. 10 is a sectional plan view, the section being taken on a line 10-10 in Fig. 9;

Fig. 11 is a face'view pf the lower 9nd .of

'a window sash illustrating a manner of ata rotatable roller, indicated in a general way by 2 (see Fig. 5) the housing being secured in position on a window frame by brackets 3 and '4. The roller 2 carries a screen (or a shade if desirable) said screen consisting of a plurality of sections 5 and 6 (Fig. 3).

To render the screen roller 2 and its housing 1 adjustable longitudinally so as to accommodate windows of different widths, the said roller is made up of a plurality of sections 7 and 8, and the housing of a plurality of sections y9 and 10. (See Fig. 5). Each housing section carries an end plate 11 having an inclined beading or ridge 12 formed therein, said plates constituting the brackets 3 Vand 4, hereinbefore referred to. As can be seen in Fig. 4, the housing 1 is provided with a longitudinally disposed slot or opening 13 for the passage of the screen or shade. As can be seen in Fig. 1, the gap between the adjustable roller members 7 and 8 is Ifilled by a sleeve I14 secured at 15 to the member 7, the adjacent ends of the members 7 and 8 being cut tc form overlapping projections 16 and 17, respectively. The sleeve 14 serves to'lieep the roller sections in alinement, at the same rtime permitting the said sections `to be moved apart yor pushed together. The sleeve 14 is slidably fitted to the roller member or section 8. It will be seen that the roller members 7 and 8 interlock so as to insure simultaneous rotation, such locking action being accomplished by the overlapping projections 16 and 17.

- Within the roller casing, we place a longitudinally adjustable spindle 18, consistking of a tubular support 19'and Va rod 20 slidably fitted thereto. One end ofthe tubular support is secured' to a block 21 carried by the roller section 8. The outer end of the rod 20 projects through a block 22 and beyond the adjacent end of the roller to form a trunnion. To rotate the roller 2 to wind up the screen or shade carried thereby, we provide a spring 23,- one end of which is secured to the roller member 8, the other end being secured to the rod 20. Upon the rod 20rwe place a thrustwasher 24, between which and the inner end of the block 22, we place a coiled spreader-spring 25, which acts to force the roller members 7 and 8 apart. The spindle 2O not only supports the spring 23 to wind up the roller, but also carries the spring 25 which acts to autQmatically spread the roller and housing members when said roller and housing mem- -bers are to be longitudinally adjusted.-

To secure the housing to a window-frame, we provide bracket supports 26 (see Fig. 6) one vonly being shown, consisting of plates turned over at one end, as atl 3() (Fig. 6.) to for-rn a pocket 31, the turned over end 32 having a recess`33 formed therein to Areceive the. beading 12 von the plates 11v at the ends of the housing 1, said beading being adapted to snap into said recess. Fig. 6 illustrates one of the said bracket supports and its bracket as connected.. The supports 26 are secured to the windowframe 34 by screwsv 35, or in any other desirable `manner.

.One of the features of our invention is vthe manner of rotatably l'supporting the roller 2. To. support the roller ,2, we prof .vide each end; thereof with a cap 36 (Fig. V5),y the outer end of which is cupped, as at 37, to receive the conveXed por-tion 38 of the adjacent end plates 11. The conveXed portions of the plates .11 and cupped ends ofthe Vcaps 3.6 are kept in engagement by meansv of the spring 25 which acts, as has been stated, to force the roller members 7 and 8v apart.

At one of its ends, the roller 2 is held in position in conjunction with the action of the spring 25, by a screw 39 which engages tlie adjacent block 21 in the roller casing. (See Fig. 5). This screw passes through the concave part 38 of cap. 3.6. and enters the end of block 21, fastening the latter to said cap, which is held to the window frame as already described. The opposite .end of the roller 2 is supported by the trunnion end of the rod 2O which passes through the end plate 11. The outer end of the rod 20 carries an inwardly tapering wing 40 which engages. a transverse slot 41 in the adjacent end plate 11. The engagement'of the said slot 41 and wing 4t) acts as an anchor for the4 spr-ing 23 when the rollery` is rotatedr by an unwound screen or'shade.V As 'can be seen in Fig. l0, the

Vslot 41 is shorter than the wing 40; hence the said wing will not be pulled through said: slot, but is. wedged therein. To. assemble the roller and screen, the said. roller rwill be inserted into the housingfmember .10 and the screw 39 applied thereto, after which the housing-member 9 will be applied, the win-g 40.? being heldy in a vertical position to aline with the vertical slot 41a (Fig. 9) which is wider than said wing. After the housing-member 9 has been applied and wing 40 slipped through the opening or slot 41a, the rod 2O will be pulled outwardly until the wing clears the plate. The wing will then be given a quarter turn and allowed to slip back into the slot 41.

To apply the housing to the window frame, the headings 12 will be slipped into the recesses 33 in the supports 26, whereupon the housing as a whole will be pushed inwardly until the fianges 42 (Fig. S) are reached.l

To secure the upper or free end of the screen or shade to a window` indicated b v 43, Fig. 11, we provide slidably connected. plates 44 and 45 adjustably seemed together by a binding screw 46 passing through a slot 47 in the plate 44 and engnging the plate 45. Each plate 44 and 45 .isheld by a clamp 48, consisting of a plate 49, secured to the window sash. and a rotatable binding clamp consisting of an ec- Veentrieally mounted rotatable fiat plate 50. The lower edge of the plate 49 is turned up as a 51 to form a seat for the turned over edges of the slidably connected plates 44 and 45.

To slidably connect the plates 44 and 45 we turn overl one edge of one of the plates as at 5 2, to form a channel to receive the turned over edge 53l of the other plate. Both of the plates are made up of thin metal turned over upon itself to form a clamping member to receive the screen sections 4 and 5. (See Fig. 12).

To apply the screens the latch or locking plates 50 will be turned to a horizontal position (see dotted lines Fig. 13), after which Ythe turned over ends of the plates 44 and 45 will be laid upon the upturned end 51 of the plates 49. (See Fig. 13). After having positioned the plates, as shown, the lock 50 will be turned to the vertical position, which will cause the plates. 44 and 4.5 to become vl'irrnly locked.

In order to permit adjustment of the roller 2 and housing 1 to a predetermined extent, we provide the member 9y with a scale 54 located adjacent a slot 55 having recesses 56` in one of its walls, a pointer and locking element 57 being carried by the Vhousing-member 10. When the housing members are moved'orslid longitudinally, the pointer 5.7 will jump. the teeth or pro- 'jections 58'. When the housing has been adjusted, the pointer 57 will engage one of the recesses- 56. and lock the housing members. together.

By referring to Figs. 3 and 11 it will be seen that the screen sections 5 and 6 overlap and hence can be adjusted without leaving any gap, therebetween. To permit the overlapped screenl members to be moved one over the other we secure the lower end of said members as shown in Fig. 3, one below the other. The lower end of each screen member 5 and 6 may be provided with slotted plates 59 to engage buttons 60 on the housing-members. n

As can be seen in Fig. 5, each roller cap 86 is provided with an annular recess 61 to receive the selvage 62 of the screen sections. As the screen rolls up, the selvage or stiffened edges 62 will make a somewhat thicker roll at this point than the remainder of the rolled screen, but the annular recesses 61 will receive said thicker portion of the rolled screen.

Having now described our invention,what we claim and desire to secure by Letters Patent is:

l. An extensible spindle, in combination with an extensible roller surrounding the same and adapted to turn therewith, an extensible housing surrounding said roller and engaged thereby to cause its extension therewith, a spring operating to extend the above mentioned three elements and another spring acting to rewind said roller and spindle.

2. In combination with an extensible roller, an extensible roller-housing surrounding said roller and engaging the same in order that they may move together in extending and contracting them, said housing consisting of two members, one of which carries an index coperating with the other member to point out the exact degree of adjustment of the roller and housing, for showing the length of the roller as adjusted.

3. A roller consisting of two slidably connected members, in combination with a housing for said roller consisting of two slidably connected members, a plate at each end of the roller connecting a member of said housing to a member of said roller in order that said housing and roller may be' 4:. The combination of a tubular shade roller, a rotatable spindle within the same, a spring to rewind said roller after having been unwound, an inwardly tapering wing carried by said spindle at its outer end, end plates attached to the ends of said roller, the plate adjacent the wing of said spindle being provided with intersecting slots, one of said slots being wider and longer than the former slot and shorter than said wing, the other slot being narrower than said wing in order that said wing may pass freely through the former slot in either direction but may be wedged in thelatter slot when drawn into the same, 4for the purpose set forth.

5. A shade-roller, consisting of a plurality of extensible members, a housing therefor distinct from said roller consisting of a plurality of extensible members, an extensible spindle within said roller, a spring carried thereby arranged to wind up Said roller after having been unwound, said spring being arranged for extension when said spindle, roller and housing are extended, and means to connect the free end of said spindle to said housing, whereby said spindle and roller will extend simultaneously with the extension of said housing.
